Description
In this talk I will describe our work on quantum networks of quantum emitters [1]. From the point of view of Quantum Optics, these are setups of quantum emitters (i.e. qubits or cavities that talk to qubits) connected by waveguides that transport photons among those nodes. This leads to a paradigm of quantum systems interacting through the exchange of retarded photons, creating what we call a non-local quantum many-body system. I will discuss the theoretical tools we have developed and how these tools can already provide insight in topics ranging from quantum state transfer among quantum processors to a new type of collective emission, called cascaded superradiance, that takes place in these networks.[1] Time-delayed collective dynamics in waveguide QED and bosonic quantum networks, Carlos Barahona-Pascual, Hong Jiang, Alan C.
